Statistics Help

**Question: **A 2003 New York Times/CBS News poll sampled 523 adults who were planning a vacation during the next six months and found that 141 were expecting to travel by airplane (New York Times News Service, March 2, 2003). A similar survey question in a May 1993 New York Times/CBS News poll found that of 477 adults who were planning a vacation in the next six months, 81 were expecting to travel by airplane. At 0.05 level of significance, is there a significant change occurred in the population proportion planning to travel by airplane over the 10-year period? Edit
